Abstract

This paper proposes a novel quantum key distribution (QKD) protocol that synergistically combines multi-particle entangled messengers with chaos-based systems. The core claim is that this integration significantly enhances the security of key distribution, offering robustness against known attack methods. The underlying mechanism involves generating highly faithful multi-particle entangled messengers, typically using sophisticated systems like superconducting circuits or optical crystals. The key distribution process then leverages the sensitivity and nonlinear characteristics of chaotic systems to correlate the quantum states of these entangled messengers with classical key information. Furthermore, the system utilizes the dynamic changes within the chaotic system to introduce randomness, thereby bolstering the security of the generated key. This approach addresses limitations inherent in traditional QKD protocols that rely on single-photon source stability and entangled messenger transmission distances. The resulting system demonstrates enhanced resilience to messenger transmission instability and offers a promising avenue for secure key exchange in challenging environments. The protocol is designed to maximize key rate while simultaneously providing a high level of security, a balance often difficult to achieve in existing QKD schemes. Mathematical models are presented to illustrate the core principles and demonstrate the potential performance benefits.
